#fuel
- Additive — A chemical substance added in small quantities to a product (such as fuels, lubricants, foods, cement, or polymers) to improve its properties, prolong its preservation, or impart new structural characteristics; as an adjective, it describes a process based on accumulation, summation, or progressive addition (e.g., additive manufacturing). This structural element is indispensable in modern industrial processes for material performance optimization.
- Additived — Having been enhanced or treated through the addition of one or more additives; it refers specifically to fuels (gasoline, diesel) or industrial oils whose physico-chemical properties have been structurally optimized during the refining or packaging stage to ensure cleaner combustion or superior lubrication.
- Aerozine — A storable, high-performance synthetic liquid fuel used in rocket and space module propulsion, composed of a 50:50 blend of hydrazine and unsymmetrical dimethylhydrazine (UDMH). This structural substance is hypergolic (ignites spontaneously upon contact with an oxidizer like dinitrogen tetroxide), being essential for orbital correction engines requiring multiple reliable restarts in a vacuum.
- Alkylate — The liquid reaction product obtained in the petroleum refining industry through the alkylation process of isobutane with light alkenes (propene, butene); a mixture of branched saturated hydrocarbons with a high octane rating, utilized as a premium component for eco-friendly aviation and automotive gasolines due to its lack of aromatics or sulfur. As an adjective/participle, it describes an organic molecule into which an alkyl radical has been structurally introduced.
- Alcohol-powered car — A motor vehicle specially adapted or used for transporting mobile blood alcohol testing units, or a vehicle propelled exclusively by alcohol-based fuels (pure ethanol or bioethanol blends). In traffic control jargon, the term can also refer to mobile police laboratories equipped with field toxicological gear.
- To feed — To provide someone with or to procure the food necessary to sustain life and organism activity; by extension, in technology, to supply a machine, engine, or structural system with fuel, energy, raw materials, or data required for operation. Figuratively, it means to maintain, stimulate, or keep alive a state of mind, a feeling, a discussion, or a tense situation.
- Supply — The act of feeding or supplying and its result; the structural process of providing food, fuel, energy, or raw materials needed for an organism or technical system to function. From a grammatical point of view, it also represents the plural form (masculine/feminine) of the adjective alimentar.
- Anthracite — The highest rank of fossil coal, characterized by an extremely high fixed carbon content (92% to 98%), a minimal percentage of volatile matter, and a distinct semi-metallic luster, representing the final stage of coalification.
- Anti-knock agent — A chemical substance or additive added to fuels to increase their resistance to premature auto-ignition and to prevent the phenomenon of detonation in internal combustion engines; a compound that regulates the burning rate of the fuel mixture. As an adjective, it describes a fuel, mixture, or structural effect capable of ensuring a smooth and efficient engine operation, eliminating parasitic metallic knocks.
- Anti-icing fluid — Preventing or impeding the formation of ice; a liquid chemical substance (usually glycol or alcohol-based) sprayed on mechanical elements or added to fuel to lower the freezing point. As a noun, it designates the protective fluid utilized in preventative airport winter treatments.
- Tanker truck — A heavy-duty utility motor vehicle equipped with a large airtight reservoir (tank), specially designed, built, and approved for the secure road transport of fluids, liquid cargo, liquefied gases, or bulk powders.
- Aviation chemistry — A specialized branch of the chemical industry and aeronautical engineering dealing with the research, synthesis, production, and testing of chemical materials used in aviation. This includes high-performance fuels, special lubricants resistant to extreme temperatures and pressures, hydraulic fluids, de-icing agents, composite resins, and protective coatings for aircraft structures.
- Bagasse — The dry, pulpy, fibrous material that remains after crushing sugarcane, sorghum, or agave stalks to extract their juice. It is extensively used as an eco-friendly biofuel for generating heat and electricity, as well as a raw material in pulp, paper, and sustainable construction board manufacturing.
